No connectivity between ups and computer

Samuel 5/2/2018 9:20 PM

My UPS automatically switches to battery mode when serial cable is connected to it, is this normal? 

More so, I've used windows 10 and also windows XP, yet I can't establish connection between my system and the ups. Is there anything I can do to establish connection?
